Refactor kitchensink watchdog tests.

- Replace existing tests with two new tests:
  - Non-recurring I/O overuse test: Kitchensink app shouldn't be killed
  on non-recurring I/O overuse.
  - Recurring I/O overuse test: Kitchensink app should be killed on
  recurring I/O overuse after display is turned off.
- Add a new TextViewSetter class to update the text view constantly and
provide the user with the current status of the test run.
- Add help tips in the error messages to help QA team troubleshoot test
failures.
- Delete temporary files as soon as the write completes to avoid
consuming too much storage when the recurring I/O overuse test runs.
- Update success alert message to clearly indicate the test run status.
- Increase the alert message font size to improve readability.

Test: Ran the kitchensink tests and verified the test completed
successfully. Verified that watchdog kills the app on recurring overuse
and after the display is turned off.

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
